I love this thread so so much! So wholesome, I might have to pop in here often. 
Here's some I can think of:
1. Listening to someone talk about something they're passionate about.
2. Learning something new and finally 'getting it' after trying again and again.
3. People expressing their love for their siblings.
4. People expressing their love for their friends.
5. People expressing their love in general 
.
6. Someone showing they thought of you in small ways e.g. sending you a meme or a picture that reminded them of you.
7. Pride and people being themselves openly, and celebrating themselves.
8. Older LGBT+ people sharing their experiences and looking at younger generations with hope.
9. People from different walks in life/ having different experiences managing to stand together in solidarity for something important to them both.
10. The feeling of reading the last sentence of a book, putting it down, and not knowing what to do or read next while you think about that little world for a while.
11. Sitting at an airport wondering where everyone else is going, knowing you're all on different journeys yet you're sharing the experience of going on some kind of journey.
12. Going on a roadtrip and listening to music really loud in the middle of nowhere, stopping at the side of the road to take a picture (recently I've also been into geocaching! So fun).
13. Seeing stars at night and being overwhelmed how big the galaxy is.
14. Looking at the moon and knowing it's the same moon everyone in history has looked up at.
15. When a whole group of people can't stop laughing at something, and the moment they stop laughing something reminds them of the funny thing and they can't stop again.
